Technology’s moved on a lot since energy saving lightbulbs were first invented, and so has the way they look. Energy-saving light bulbs now come in all shapes and sizes. Depending on how long your lights are in use every day, just one energy saving lightbulb could save you up to £7 and 26 kilograms of CO2 a year. As well as energy consumption, criteria for lightbulbs also covers how long they should last, quality of light, packaging information and safety. Light bulb manufacturers include this information right on the product packaging to make it easy for consumers to choose the equivalent bulb. Some jurisdictions have or are considering banning the sale of incandescent lightbulbs in favour of more energy efficient lighting.
There are now more good reasons than ever to buy energy saving lightbulbs. Energy saving light bulbs use a fifth to a quarter of the electricity of ordinary bulbs to generate the same amount of light. In other words, they can help you to save money and energy, all in one wise purchase. And by saving energy, you’ll be helping to fight climate change too. Advances in technology mean that energy saving lightbulbs are now available in a wide variety of fittings, shapes and sizes. In turn, using less energy like electricity means that our homes produce less carbon dioxide: one of the main causes of climate change. Next time you need a bulb, buy an energy saving one.
Don’t stay in the dark. If every American home replaced just one light bulb with an energy saving bulb, we would save enough energy to light more than 3 million homes for a year, more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars. Due to the higher energy usage of incandescent light bulbs in comparison to more energy efficient alternatives, like compact fluorescent lamps and LED lamps, some governments have passed laws and regulations that have started to phase out their usage.
